BURNER APPARATUS.

Application led November 28, 1927. Serial No. 236,252.

My invention relates, more particularly, to oil burning apparatus of the type involving, as an element thereof, a part which, to prop rly function, inust extend in horizontal position, such as for example agenerator plate to which the ituel oil is ted and over which the oil flows as exernplilied in iny United States Letters Patent No. 1,627,267, granted May 3, 1927.

rl`he invention relates further to burner structures which are set into the lower por-v tions of furnaces and are sealed therein against flow of air upwardly into the furnace about the burner, except through such openings :is may be intentionally provided for supplying,` air to the burner, an exemplii'leation of such an arrangement being dis closed in iny seid Letters Patent, in which case air duets opening through the bottom or" the burner structure und extending upwardly into a position Atobe heated by the combtistion oiE the fuel at the btu'i'iei'and supplying heated oir to the burner, are pro-` vided.

` ln such structures it is very dit'licult, ijl not impossible, in sonne instances, to effect the proper leveling` or the parts, such as the generator plate referred to, required to be level to properly function, and once installed and sealed no further adjustment ot the burner structure to level such parts, either initially or later in case or' displacement or replacenient otter removal, as for example for repair or cleaning, is possible.

My primary object is to provide burner structures ot such construction that they may be properly sealed into furnaces and still permit of the accurate leveling of the parte required to be in levelcondition .either initially alter sealing or later, es in the ease ot' displacement or replacement after reinoval.

Another object is to provide n simple und economical structure of burner apparatus which may be readily installedin a 'furnace und scaled in position therein; and other objects will he manifest frein the following` description.

Referring to lthe accon panying ings?-V Figure l is a view in sectional elevation of the lower portion ot u furnace shown as equipped with iny improvements shown in elevation and partly sectional; and Figure 2 is a plan diagrammatic View ol parts of the structure et Fig. 1,`this view showing the base of the burner structure in plan as viewed freni section line 2 on Fig'. l and in the direction of the arrow, supplemented Vby a showing` in plan, part-ly by dotted lines and partly by full lines, ot' certain parts above the section line. Y

The burner structure proper shown, vwhich is ot' the general type disclosed in my. said Letters Patent and functions in the same way, coinprises'a base portion 3 and asuperposed manifold portion at shown as supported thereon, the base portion 3 being torined at its center with an inverted bell portion 5. The bell portion 5 is centrally apertured as represented at 6 and screwed into the opening thus provided is a pipe section 7 containinga series of radially Vdisposed openings 8 in its side wall opening into the interior of the bell Screwed upon theA .upper end of the pipe section 7, and vertically spaced from the bottom of the inverted bell portion V5, is a burner heet in the orrn ot'a generator plate 9 preferably of the circular stepped form, as shown, with the upper surface ol" each annular step portion annularly grooved as represented at 10, this being the part of the burner structure shown which it is required be in level position to cause the burner to properly function. The generator plate 9 contains a centrally disposed aperture ll in which the open, upper, end of an oil pipe l2 is secured, the oil to be gasilied being supplied to the upper surface of the pluto 9 through this pipe which latter extends downwardly through the pipe 7 and in spaced relation thereto as shown.

A pipe section 5 screws at its upper end into the lower end oit the opening,` 6 in the bell 5 and at its lower end into an opening 18 in the top of a cross-fitting lll, the lower opening,` l5 in which has screwed into it a threaded pipe section 16 which latter is screwed at its lower end into an opening- 17 in a Tlitting' 18 screwed on the upper end of a pipe 19, supported as hereinafter described, the oil pipe l2 extending downwardly through, and in spacedrelation to, the hollow ineinbers just described and laterally outward through an opening 2O in the "t-fittinfz; 18 and through a pipe 2l screwed into the opening 20, this pipe thence leading to e suitable supply of fuel oil. y

The manifold section 4l contains a. passage 22 opening at its opposite ends through the base plate 8, and terminating midway between the ends of the manifold in e downllO " With continuous upwardly opening-recess,

Wardly opening portion 23 arranged directly over, 4and concentric with, lthe generator plate 9, the purpose of providing' this manifold being to direct air, which rises up- Wardly through its inlets and thence passes downwardly through the passage 23 and which thus becomes heat-ed, to the generator plate 9 for inixturevwith the oil supplied to this plate. Y

i The burner alsofcoinprises a pair of pipes 24 each of inverted U-shape which are located y at oppositesidesof` ther manifold a and each through the baseplate 3.

of Which opens at both ends downwardly @ne end of each of theVV U-pipes 24 is left open, VWhereas the other ends of these pipes open into the pipes 25 which i'nturn openinto the fitting 13, the purpose ofthe pipes just referredto beingtoconduct air entering them through their lower open ends,through theheated portions of these pipes and thence into the space sur-L rounding the oil pipe l2Y for heating the oil in the pipe 12 in its passage to the generator plate and furnishing a supply of heated air be` loiv andaround the burner head, theair dis chargingthiough the ports 8, andsupplemenvtai-y to that` suppliedto'the generator plate from above through the manifold Ll.

The outer end ofthe pipe 2l is shown as provided with a hollow head 2G through which the pipe l2 extends, this headcontaining an opening 2'?, located in position todis chargel oil overifiowii'igthe burner head, into the drip bucket 28 of*drip-bucketcontrolled mechanismprovided to automatically shutoff v the fioiv of oil to tliefpipe l2 in caseof overflow of oil from the burner, the bucket 28 being shoivnas `hung on anend of a trip lever 29 controlling a shut-olf valre represented at 30 controlling the supplying ofoil throughtlie pipe l2 as isivell known in the' art. j A The burner structure shown also comprises a supporting base '3l having an upwardly ex- Y tending socket 32 into which the lonier end of the pipe l) entends and to `which it is secured,` to periiiitof its vertical adjustment, by asetscrew t i. The base 3l is provided with vertically'adjustable 34 shown as set-screws arranged in triangulaiforin at uhich'the base rests upon thepart on which itis to be supA ported, the adjustable legs 3l aifording means wliei'ebytlie base plate 3 and the partscarriee thereby may becaused to extendin level posiv tion, regardless the position occupied by the support Aupon which thebase-3l rests. Y

Referring now to those'features of the ccn-' struction shoufnjvhicli constitute my invention,.the apparatus illustrated alsocoinprises aV frame member of the as the baseplate 3 and provided along its sides or channel, 36, into which anl endless flangemember V537 depending from the marginal Vedges of the base plate 3, looselyextendsper initting of tilting movement of the base plate same shapein plan 3 on the frame 35, and forming in 'effect a relatively loose telescopic joint between these parts.

The frame35 issuppo-rted on standards 38 showvn as rising from. a base plate 39 in a triangulararrangement, the base plate 39 being adapted to be seated on the vfloor of the ash pit of the furnace to'be equipped with the apparatus. The standards'shown are each formed ofV a lower tube sectional) andan upper rod section ll loosely teleseoped therewith, with Y the lower end of the latter threaded, as representedat 4t2 for engagement with a nut i3 which rests on the upper end `of the tube 40 and by the adjustment of which on the rod 41 varies Ythe elevation ot'tliese rods, these adjustable supporting means permitting the frame 35to be substantially horizontallyposi-V tioned inthe furnace, such as that represented at da and in whicli the apparatus is shown installed.

ln the arrangement shown the frame 35h] the installing' of the apparatus in a furnace and which is positioned therein to be spaced at allrsides from the side Walls 'of the furnace shown, is sealed therein to close the space around theframe 35, as by cement,"represented at l5 which is'pouredf Vupona inold-bottom-foriningmember lo located in the spiace between the frame and the furnace lWalls,V the cement when it hardens permanently sealing the frame 35 in place.

ils. a convenient means for supporting the member 46 during the pouring ,of the cement l provide on the frame 35, to radiate from the center thereof, threaded studs @i7 which are.

`slidable in radially disposed Yopenings Lll'in the frame 35 and extend loosely through slotsv l'ain the flange 3701i the base. 3 when the base is assembled `with the frame 35, these studs having nuts 49 screwed thereon and extending at the outer vand innersides, respectivelyyof thefraine135. ln tlieinsertion of the frame to positionfin the furnace, usually through the ash )it opening at the front of the furnace, the studs are preliminarily adjusted inwardly toward the centerof the frame 35 and; after the member i6 is applied to encircling position about the traine 35, the studs 4l? areadj usted outniai'dlyto .the positionslioivn, to' form seats for the member 46, whereupon the'cement .45

`is pointedy sealing 'all of these parts in place.

ln thearrangement shownthe base plate 39 is of such size that it furnishes a support upon which theffeet 3a- `restand against Vwhich the latter are adjustable;

lio

The base plate 3 of the burner structure andv carrying the generator plate Sto be leveled,`A being tiltably adjustable relative to the trame 35: in the permanently Vsealed coi'idition of the latteiginaybe adjusted at ivill either tofi'n'iff ltially, or.subsequently,level it, and byreason ofthe loose telescopic joint between the base plate andthe frame' 35. such adjustment may VVbe Vmade Without danger of opening the joint moines between these parts and permitting,v of the leakage of alrupwardly therethrough.

ldhile It have illustrated and described a particular construction embodying my invention, I do not Wish to be understood as intending to limit it thereto as the same may be yariously modified and altered without departing from the spirit 'otlmy invention.
